Cornelius police are searching for a suspect who robbed a store at gunpoint while dressed in a ski mask and trench coat.

Shortly after 9:30 p.m., a man, armed with a handgun, entered Baseline Market and Deli, and ordered the clerk to open the cash register, said Lt. Joe Noffsinger, a Cornelius police spokesman. The man took an undisclosed amount of money and fled from the store, located at 1206 Baseline Street.

Officers used a police tracking dog to try to find the suspect, but their efforts were unsuccessful. Noffsinger said investigators think the man left in a vehicle because the tracking dog did not lead officers anywhere. Police do not have a suspect vehicle description.

As officers searched for the suspect, they contacted a man, who had a felony warrant for his arrest, Noffsinger said. Police do not think the man, who was taken into custody, is responsible for the robbery.
